Question 779180
Let {{{ f }}} = the usual fee to train puppy
{{{ f - .23c }}} = the discounted cost
{{{ f - .23c = f( 1 - .23 ) }}}
{{{ f( 1 - .23 ) = .77f }}}
---------------------------
given:
{{{ .77f = 379.98 }}}
{{{ f = 493.48 }}}
--------------------
The usual profit is
{{{ 493.48 - 349.99 = 143.49 }}}
$143.498
-----------
The problem could have been worded better.
It should have said " the cost to the trainer
of training a puppy for 10 days is $349.99
